1.5" to 2" Piping for Pump/Filter Help

[ctrinh]

Hi All,

Been lurking around the forum for information throughout the past 2 years of ownership and the forum have helped out a lot! Before we get started, pool/equipment specs:

Inground Pool: 22,600 gallons
Hayward Super Pump 1HP
Hayward C3030 Cartridge Filter

Previous owner used a Hayward above ground PowerFlo Matrix 1.5HP pump and EC50AC for the unground pool. Worked great for the 2 years and water was clear. This year there were air leaks in the pump/DE returning to pool/high pressure/weak jet return. Did some diagnosing myself with the suction side and thought I get the correct pump for IG pool. Ended up with the Super Pump 1HP. For the DE return to the pool, I changed a few fingers, got new unions, gaskets, etc. Fixed the DE issue but still high pressure and weak jet pressure. Found out that the grid fingers need replacements and the price was quite a bit for all 30. Decided to buy a new filter. Ended up with the C3030.

My issue now is the line coming out of the group is 1.5" flex piping. Do I attached a union to it to make it 1.5" to 2", and then 2" from pump to filter? The return line to the pool is also 1.5, so will probably do the opposite 2"- 1.5". Is that correct without changing the underground pipings? Another way is to return the filter and get the DE3620 which is 1.5" all around. Any suggestions would be appreciated and thank you in advance!

You can get schedule 40 pvc adapters to go from 2" to 1.5". Are the ports on the filter threaded inside and out or is one side smooth?

Bigger is better

The ports on the filter is threaded on the outside I believed (it's coming tomorrow). The pool store guy told me to get a few feet of schedule 40 pvc pipe (in case I messed up) and attached that to the pump outlet to the filter. Pump outlet is 1.5". Also the return line back to the pool is only 1.5" also, so the only piece that need changing to 2" is from pump to filter and from 2" to 1.5" is filter to return line. Pics below.

All said and done, was thinking I should've went with the DE3620 which have 1.5" piping throughout instead of this. I can still return it and get the DE, thoughts?

Update:

Spent 1.5 hours this morning working on this. Phase 2 will be using the other return line that was not hooked up so I can have 3 jets instead of 2. Also the drain suction was not attached and will be included in phase 2.

A newbie mistake, purchased a 10' PVC thinking it will fit in the car. Lay it on the dashboard from the trunk and while closing it, cracked the windshield. Went back in to HD and had them cut the pipe.

So far the new cartridge filter is running at 12-13PSI. Return jets are strong.

Looks good. Bummer about the windshield. Are you sure it wasn't that big cement truck that kicked up a rock?

You should have taken the time and repiped the whole thing. You've got flex pipe mixed with black rubber sleeves with collars and the worst part is you have 90 degree elbows right before the pump and on both the inlet and outlet of the filter. You could have easily turned the filter 90 degrees so both the inlet and outlet were facing the pipe coming from the pump. Also, a nice straight run of PVC before the pump inlet would help reduce water turbulence. From the looks of it, you've got plenty of space on the equipment pad to put everything the way you want it and make it look really clean.

Agree with the above comment. If you turn everything and a couple of couplers you should be able to hook everything direct and get rid of that elbow and most of that flex on the outlet. Just a suggestion as well i would get rid of that rubber mat under the pump and at least make a pressure treated surface out of 2x6 or something so you can bolt the pump down. Over time with the vibration of the pump it could cause a crack in your pump piping.
